Yelp's Anti-Spam Review Filter

Reviews may come or go for a few different reasons: 1. A user may have removed his or her review.
2. Yelp may have removed the review for violating our Review Guidelines or Terms of Service (in which case we will typically notify the reviewer).
3. Yelp has a system which automatically determines which reviews show for a given business. Just as your Yahoo or Gmail email account doesn't deliver every email (spam, etc.), we don't show every review. This protects both business owners (by suppressing reviews that may have been written by a malicious competitor, for example) and consumers (by suppressing reviews that may have a definitive bias, having been written by owners or their friends). It's important to note that these reviews are not deleted (they are always shown on the user's public profile) and may reappear on the business listing page in the future.
